- In your list, we advise you not to include more than 2 destinations that are classified as Chances of placement: low.
- Only select destinations that you would be happy to go to, even if they are not your first choice.

If you need further explanation, consult the Manual on applying for university-wide exchange via uSis.
You may only go on exchange with the approval of your study programme. Once you submit your application, the international exchange coordinator will ask your programme to confirm its approval.
Note that the selection procedure has changed! See explanation below.
For further details and background, see University-wide exchange - Lottery procedure.
Once your programme confirms its approval, we will check you meet the eligibility requirements. We will also review your letter of motivation to make sure your study abroad plans are realistic and achievable and your choice of universities is well considered. If we have serious doubts, we may contact you to discuss your plans.
You will then be included in the selection process. For university-wide exchange, selection takes place via a lottery procedure.
Lottery procedure
- If there are sufficient places available for all applicants at your first choice of destination, you will be placed there.
- If there are insufficient places, these will be allocated via a lottery procedure. All students will be allocated a random ranking number via an automated programme.
- Starting with ranking number one, we will check if we can place the student at their first choice of destination. If not, we will try to place them at their second choice, then their third and so on. The same will be done for all students in order of ranking number.
If you are offered a place, you will be invited to log into the study abroad portal to view the details of the offered place. Make sure to read all the information and conditions of the offer carefully.
In the unfortunate event you cannot be placed at any of your chosen destinations, you will be invited to take part in a second selection round for the remaining available places.
If you have been offered a place, you must accept or decline it within 7 days in the uSis study abroad portal. If you do not accept the offer on time, it will be withdrawn. When accepting your place, you must agree to the Regulations on Studying Abroad. Be prepared and read these in advance. If you have any questions about the regulations, contact your international exchange coordinator.
Once you accept your place, Leiden University will nominate you to your host institution. You will then receive instructions on how and when to submit your application to your host institution, either from your international exchange coordinator or directly from the host itself.
Approval
Study Programme Approval
Before applying for an exchange, you must inform your study advisor about your plans and make sure you get approval for an exchange. This doesn’t have to be official approval from the Board of Examiners yet.
Requirements
To apply for a faculty exchange programme, you must meet the following requirements:
- You are registered as a student at the Faculty of Science at Leiden University before and during your exchange;
- Your study programme agrees with your plans to study abroad;
- You have passed all first-year courses (propedeuse);
- You are a nominal student; and
- You preferably have a GPA of 7.0 or higher.
Students with a lower GPA may apply, but your application will be discussed with the study advisor and you may not be eligible for all partner universities.

Application Documents
Please upload the following documents with your application:
- A motivation letter in which you explain your motivation for your top choice or your top 3 choices.

Find more information on the requirements for each of these documents under ‘Steps to Take’, below. Struggling with your motivatoin letter? Sign up for our workshop, hosted by Science Career Service, here.
Steps to Take
You may only go on exchange with the approval of your study programme. Inform your study advisor about your plans and make sure you get approval for an exchange. Once you submit your application, the international exchange coordinator will ask your study programme to confirm its approval.
After looking through all the options in the world map, draw up a list of (up to) 3 universities where you would like to study, in order of preference. Please note that submitting fewer will not increase your placement odds. Please do not submit more than 3 choices – if we cannot place you within your top 3, we will contact you with alternatives.
Letter of Motivation
Write your letter of motivation. There is no template for the faculty exchange programme, you may format your letter as a standard letter of motivation. You may explain your motivation for your top choice or your top 3 choices. Please stick to one A4-page!
Your letter should include:
- Your name and study programme
- Academic motivation
- Why do you want to study at your host university? What area of study will you be pursuing? What courses at the partner university align with this?
- How does an exchange fit into your programme at Leiden University? Will this be during your minor period, or, for example, extra-curricular?
- For non-English speaking destinations: why is your Italian / French / German / Spanish sufficient to take courses at university-level abroad?
- Personal motivation
- Why do you want to go on exchange? What are the (non-academic) reasons for choosing this particular university / city / country?
Second Semester as Plan B
Are you applying for the first semester, but can you also go abroad in the second semester (or vice versa)? Mention in your letter that you wish to be considered for a different semester if you are not selected for your first choice of semester. Please note that it is important to discuss this with your study advisor in advance to make sure your study programme permits going on exchange in the second semester.
Study Plan
Make a (prospective) study plan in which you outline which courses you would like to follow at your top 3 choices. This is not a final study plan, but an indication of your interests. You do not need to include the complete overview of courses in the main text of your motivation letter. You may upload the study plan as a separate document, or add this to your motivation letter document, after your main text.
We ask that you make a study plan to be sure an exchange fits into your study programme. Are enough courses available in your field of interest, at your study level, and in a language you speak? Consider which compulsory courses you still need to complete in Leiden, how semester dates align and when exams are scheduled.
